The Atomweight division (102lbs) is the smallest weight class in professional boxing and is a division that only has females compete in it. Despite being the smallest division it has one of the longest reigning world champions in all of professional boxing, Momo Koseki (18-2-1, 5).

Koseki, the WBC Atomweight champion, is unbeaten since 2007 and has been a world champion since 2008. Earlier today she recorded her 13th world title defense, equalling the national record held by Yoko Gushiken, as she stopped the previously unbeaten Thai Angor Onesongchaigym (5-1, 3) in impressive and one-sided fashion.

Angor, reportedly a former elite level Muay Thai fighter, was seen as the big under-dog before the opening bell and by the end of the opening round things proved to be as one sided as we expected.

Koseki looked confident from the off and swiftly took control of the bout. She applied careful and intelligent pressure and swiftly forced Angor on to the back foot. Although this was expected it was simply happening too easily for Koseki who had quickly began to assert her dominance on the Thai youngster.

Angor, looking out of her depth, tried at times to fight back but she simply couldn't do anything to dissuade the teak tough Koseki from walking her down. It was obvious that this was a girl against a woman and when Koseki continued to walk through the bigger shots of Angor it really didn't look good for the Thai challenger who resorted to holding. It had quickly turned from Angor trying to fight back to Angor trying to survive.

The Thai's bravery was impressive though it was all in vein. She was a mile down on the scorecards, wilting and being beaten up by Koseki through the middle and later rounds. With her domination of the bout it seemed that Koseki felt the urge to hunt a stoppage and put an exclamation mark on the performance.

It seemed that the challenger was going to reach the final bell but then Koseki turned it up, launching a huge attack in round 9 that eventually forced the referee to step in and call a halt to the proceedings to save the Thai who was taking shots with out throwing much left. It was late in the day though with another round to go it was a stoppage that saved the out classed Angor from further punishment

Although Koseki accepted that her 13th defense was impressive she also accepted that it wasn't as important as Gushiken's record and suggested that there was a big difference between men and women. Although that's true it's still a very impressive achievement from Koseki who hinted that she wants to return to the ring soon to make her 14th title defense and make a new record breaking that of Gushiken.
